The CA306 piezoelectric accelerometer is a high-quality, high-reliability vibration sensor with a piezoelectric sensing element that provides a charge output. Accordingly, an external charge amplifier (IPC704 signal conditioner), is required to convert this charge-based signal into a current or a voltage signal.

The CA306 is designed and built for long-term use in extreme environments characterised by high temperatures and/or hazardous areas (potentially explosive atmospheres).

FeaturesDesigned for the long-term measurement of vibration in extreme environments, such as aero-derivative and industrial gas turbinesHigh sensitivity: 50 pC/gWide temperature range: ?55 to 500 °CAvailable as a sensor only (no integral cable) or with an integral mineral insulated (MI) cable with a flexible stainless steel overbraidCertified for use in potentially explosive atmospheres
